Unihertz Jelly 2. Much better than K-touch i9 -- larger memory, larger storage, and much faster SoC. The screen resolution is also way higher. It comes with Android 10, which means installing Android 11 GSI would be a breeze.
The next major release of Shelter will have a completely revamped on-boarding process. I hope that this will make the initial setup less confusing and I will receive less bug reports due to mere confusion.
